I want to pass log file as an input to a Logstash input. I have added /bin to the environment variable path so that I can access it from anywhere.
Below is my conf file:
logstash.conf
input{
path => "D:\nest\es-logging-example\log\info\info.log"
start_position => beginning
}
output{
elasticsearch{
hosts => ["localhost:9200"]
index => "indexforlogstash"
}
}
After running this using logstash -f "D:\nest\es-logging-example\logstash.conf" its showing below error in terminal.
`

What is this error about?
I think your problem is that the \ is an escape character in the quoted string in your config file.
Can you change
path => "D:\nest\es-logging-example\log\info\info.log"
to
path => "D:\\nest\\es-logging-example\\log\\info\\info.log"
So the \ characters in the path are escaped.
There's no configuration found in C:\logstash-8.1.0\logstash.conf
Specify the absolute path where your logstash.cong file is located instead:
logstash -f "D:\\nest\\es-logging-example\\logstash.conf"
You also need to modify your config file as follows
path => "D:\\nest\\es-logging-example\\log\\info\\info.log"
Your configuration is wrong, you need to specify which input plugin you are using, which based on what you shared is the file input plugin.
Also, you need to use forward slashes.
Try the following:
input {
file {
path => "D:/nest/es-logging-example/log/info/info.log"
start_position => beginning
}
}

I am a novice in the world of LogStash. Just started to learn it. I tried to create a config file called Unhealthy_data.config using data from a similarly named csv file.
The contents of my config file are as below: -
input{
file{
path => "D:/01_Users/LogStash/Unhealthy.csv"
start_position => "beginning"
}
filter{
csv{
separator => ","
columns => ["cluster_name","unhealthy_nodes","userid","applicationid","queue","application_type","impact_host","cluster_utilization","queue_utilization","running_containers","running_memory","elapsed_time","tech_datestamp"]
}
}
output{
elasticsearch{
hosts =>"http://localhost:9200"
index => "unhealthy"
document_type => "unhealthy_data"
}
stdout{}
}
}
The last column "tech_datestamp" is a Date column.
I am unable to load the data and get the error as below: -

You have not closed your input section before opening your filter section. As a result, the logstash configuration compiler interpets the csv filter as a csv input
Try moving the final } to after the filter section.
I am trying to get the logs from logstash and send it to elasticsearch for visualising the logs using kibana but I am getting an error while running this code from logstash\bin directory
logstash -f logstashpipline.conf
The error says
Error: Could not find or load main class MyPC\Desktop\logstash\logstash-core\lib\jars\animal-sniffer-annotations-1.14.jar;

This is my code:
input {
file {

type => "apache_access"
start_position => "beginning"
}
file {
path => "C:\xampp\apache\logs\error.log"

}
}
output {

}

}
this is the problem of 6.4.1 version of logstash.bat: redundant quotes are applied for %CLASSPATH%
So, you can fix it manually by editing logstash.bat file. Find and replace this line
%JAVA% %JAVA_OPTS% -cp "%CLASSPATH%" org.logstash.Logstash %*
with that one
%JAVA% %JAVA_OPTS% -cp %CLASSPATH% org.logstash.Logstash %*
You can try this to solved your problem as I had also the same problem and solved it.
If you are using windows, try to remove the space from path, move logstash to folder C:
Use:
logstash.bat -f logstashpipline.conf
Instead of:
logstash -f logstashpipline.conf
I come here after reading How to reference environment variables in logstash configuration file?.
Unfortunately it did not work for me.
I am running:
bin/logstash -f my_filters.conf --debug
And my config file is:
input {
file {
path => "/tmp/${RUN_ID}/*.txt"
start_position => beginning
sincedb_path => "/dev/null"
ignore_older => 0
}
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
index => "${RUN_ID}"
}
}
And no new index is being created.
This is after setting:
export RUN_ID=500
For example.
If I change my config to have a hard-coded value (e.g. 500), then the index is created without a problem.
I have read the documentation and it mentions exactly what I'm doing right now...
What am I doing wrong, how can I get the environment variable working?
Logstash 2.4 requires a command line argument of --allow-env to do environment substitutions.
Without the flag it doesn't complain (but doesn't work)
bin/logstash -f test.conf
Settings: Default pipeline workers: 8
Pipeline main started
With the flag, it will complain if you don't set it:
bin/logstash --allow-env -f test.conf
fetched an invalid config {:config=>"input {\n file {\n path => \"/tmp/${RUN_ID}/*.txt\"\n start_position => beginning\n sincedb_path => \"/dev/null\"\n ignore_older => 0\n }\n}\n\noutput {\nstdout { codec=>rubydebug}\n elasticsearch {\n hosts => [ \"localhost:9200\" ]\n index => \"${RUN_ID}\"\n }\n}\n\n\n", :reason=>"Cannot evaluate `${RUN_ID}`. Environment variable `RUN_ID` is not set and there is no default value given.", :level=>:error}
And of course with the argument and flag, everything works right:
export RUN_ID=10
bin/logstash --allow-env -f test.conf
Pipeline main started
{
"message" => "asdfasdf",
"#version" => "1",
"#timestamp" => "2016-11-01T21:10:15.964Z",
"path" => "/tmp/10/test.txt",
"host" => "XXXXXXXXX.local"
}
I was learning logstash. Have a very simple config file..
input {
file {
path => "D:\b.log"
start_position => beginning
}
}
# The filter part of this file is commented out to indicate that it is
# optional.
filter {
grok {
match => { "message" => "%{LOGLEVEL:loglevel}" }
}
}
output {
stdout { codec => rubydebug }
}
The input file is just this:
INFO
I am running logstash on windows and the command is
logstash -f logstash.conf
I expect the output to be shown on the console to ensure that its working. But logstash produces no output, just the logstash config messages..
D:\Installables\logstash-2.0.0\logstash-2.0.0\bin>logstash -f logstash.conf
io/console not supported; tty will not be manipulated
Default settings used: Filter workers: 2
Logstash startup completed
I have deleted the sincedb file and tried. Is there something that i am missing?
I think this answers your question:
How to force Logstash to reparse a file?
It looks like you are missing the quotes around "beginning" and the other post recommends redirecting sincedb to dev/null. I don't know if there is a windows equivalent for that. I did use that as well, and it worked fine.
As an alternative, what I do now is to configure stdin() as input so that I don't have to worry about anything else.
When I run a command like this(on a Windows System):
logstash agent -f logstash-simple.conf
When the logstash config file had input as stdin{} it gave the expected output but when the input was a path to the input file (file{path=>})
it didn't give any output.
Here is my config(logstash-simple.conf) file:
input {
file{
type=>"syslog"
path=>["C:/Users/Administrator/Downloads/syslog.txt"]
}
}
output {
stdout {
codec => rubydebug
}
}
If you have an existing file that you are looking to load, you'll need to add
start_postition => beginning
to your file input.
I had the same problem.
You should have an empty line at the end of the file!
that worked for me
